SPECIFICATION 'orming part of Letters Patent No. 356,638, dated January25,1897.

Application filed Decembcr'l', 1885. Serial No. 220,919. (No model.)

To all 10720722, it may concern.-

Be itkuownthat we,Gnoaen HENRY Wamwnrsnr and Pn'rnn JACKSON ROYALL, ofWilson, in the county of \Vilson and State of North Carolina, haveinvented certain new and useful Improvements in Cultivators; and we dohereby declare the following to he a full, clear, and

exact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it, reference being badto the accompanying drawings, which form part of this specification.

Ourinvention relates to an improvement in cultivators; and it consistsin, first, the corn- :5 bination of the point which is provided with asingle ear, lug, or projection, the front also provided with a singleear, lug or projection, and the standard, the ears or lugs of the twoparts being made to catch upon opposite sides of the standard andsecurely fastened in position by means of a single clamping-bolt; second, the co mbinatiou of the shoe provided with openings into whichproject suitable points,with the wings, which are applied to oppositesides of the shoe and fastened in position by means of suitableclamping-bolts, as will be more fully described hereinafter.

The objects of our invention are to fasten the point on the front of theplow by means 0 of only a single bolt, which is passed through earsformed on the two parts, and'which bear against opposite sides of thestandard, and to form points or projections in the openings, so that theclamping-bolts which hold the wings 5 in position will have to catchabove or below the points, and thus regulate the height at which thewings are placed and the quantity of earth which is being thrown towardthe \plants.

Figure l is a side elevation of a cultivator to which our invention isapplied, one of the wings being removed. Figs. 2 and 3 are perspectivesof the plow-point and the front taken from their rear sides. Fig. 4 is ahorizontal section taken through the standard, showing the pointand thefront in position.

A represents the standard; B, the shoe; C, the brace; D, the beam, and Ethe handles, all

of which may be constructed in any suitable 5o manner. The point G andthe front H are made in separate and distinct parts, and each one isshaped on its rear side so as to fit on the front edge of the standardA. The point is provided with a single ear, lug, or projection, Lwhichfits against one side of the standard, and the front is provided withanother car, lug, or projection, J ,which fits against the opposite sideof the standard, and the point and the front are secured rigidly inposition upon the standard by means of a single clamping 6o bolt,L,which is passed through the standard and. the two cars, as shown. Theear, lug, or projection upon the point projects up above the upperedgeof the point, and the ear, lug, or projection upon the front extendsdown he low the lower ed go of the front, and the openings in these twocars come just opposite the opening through the standard, so that asingle bolt can be passed through the three parts, and thus clamp themsecurely together.

Through the shoe are made the two openings 0, and projecting into therear side of each of these openings is a point or extension,P, for thepurpose of dividing the opening into two parts and causingtheclalnping-boltsQ to catch either 7 5 above or below these points,according as the wings are to be raised or lowered, for the purpose ofsweeping (more or less) earth toward or away from the plants, as may bedesired. Each one of the wings It has its inner end, S, formed so as tobear against and extend parallel with the shoe, and each end is providedwith a bolt-hole, through which the clampingbolts Q are passed. Thepoints or projections which extend into the openings at their rear sidesserve to compel the bolts to remain either above or below theseprojections, according to the position in which the wings are adjusted,Should it be desired to raise the Wings upward, so that there will notbeso much earth o thrown toward the plants, the bolts are passed throughthe openings above the points or projections, and these points willprevent the wings from dropping downward in the openlugs.

If ,it is desired to lower the wings so as to move a greater quantitytoward the plants, then the bolts will be passed through the openingsbelow theprojections, and these projections prevent the bolt from risingupward in 100 the openings in case the nuts should work slightly loose.

If the points or projections were not used,;

as soon as the nut worked slightly loose upon the bolts the pressure ofthe earth upon; the wings would be apt to either move them up or down,and hence they would not remainin the position into which they wereadjusted.

These points serve to prevent the bolts from either moving up or down inthe openingsnine less especially adjusted. v

Having thus described our invention, we claim- 1. The combination of thestandard, the point provided with an ear, lug, or projection,

the front provided with an ear, lug, or projection, and theclampingbolt, the ears or; lugs of the two parts being made to catchupon 0pposite sides of the standard, so as to be clamped In testimonywhereof we affixour signatures in presence of two witnesses.
